Pegasus HABD / HWD
Hot axle box / Hot wheel detector
Description
Greater train speeds, greater axle loads, as well as the use of different coach types, demand innovative systems. ITSS has developed Pegasus, a system which meets the highest safety standards and, at the same time, takes into account the pressure of cost under which railway operators work today.
The Pegasus System identifies and records all standard axle types and braking systems. It detects hot bearing boxes and defective brakes with high reliability and the key to the impressive price-performance ratio of our Pegasus system is its modular design. There are 10 beam scanners scanning all standard axle-bearing types over a maximum width of 140mm, capable of detecting any hazardous conditions. Also, state-of-the-art infrared and digital technology ensure the rapid and precise processing of the measured values.
The PEGASUS hot-box detector is the only system on the market equipped with a special VIBRATION SENSOR. This sensor measures the influence of the vibration caused by the train on the system. This vibration can potentially cause gradual damage that can go unnoticed to the system. The damage becomes evident only when the system fails because it has been destroyed. However, if the influence of the vibration is monitored, then timely intervention will prevent premature damage to the system. Important: this use of a vibration sensor for hot-box detection has a European patent. This unique function is protected by a European patent (EP 1772342)
- The operating system used by PEGASUS is LINUX which is more reliable and less susceptible to viruses than the Windows operating system
- PEGASUS is the only system on the market which offers scanning facilities using up to 10 beams (extending 8-beam scanning to 10-beams is an option which only ITSS offers at this time – other systems usually offer only 4 or a maximum of 8-beam scanning)
- Pegasus identifies and records all standard axle types and braking systems. Hot bearing boxes and defective brakes are reliably detected.
- Automatic identification of locomotives, coaches, and train compositions.
